SPRING-CUSHION CONSTRUCTION.

Application filed October 27, 1924. Serial No. 746,182.

To all whom it may concern.

Be it known that I, Turn HEATH MACE, a citizen of the United States, residing at Las Cruces, in the county of Dona Ana and State of New Mexico, have invented new and useful Improvements in Sp ing- Cushion Constructions, of which the followinc is a specification.

This invention relates to cushions for chairs, motor vehicles and the like, and has for its object the provision of a novel cush- 1011 construction embodying a plurality of s rings for giving the necessary resilience, the construction and arrangement of the parts being such that the springs will be roperly held and prevented from punchmg through the padding as so frequently occurs after prolonged use.

Another object isthe provision of a seat cushion construction in which all the parts are interlocked whereby displacement of any will be positively prevented even under the most adverse conditions.

An additional object is the provision of a seat construction which will be simple and inexpensive, highly efficient, durable in service and a general improvement in the art.

lVith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, wherein Figure 1 is an elevation of a seat cushion constructed in accordance with my inven tion, a portion thereof being broken away and in section to disclose the internal con struction.

Figure 2 is a cross section.

Figure 3 is a detail section showing the mounting for one of the springs, and

Figure 4 is a fragmentary perspective view of one of the holding strips.

Referring more particularly to the drawings, I have shown the frame of the cushion as comprising upper and lower sets of serpentine strips arranged in pairs as shown and in crossed mating relation, the strips of each pair being riveted or otherwise secured together at the points of crossing as shown at 11. The ends of the strips of each pair are out-turned as indicated. at 12 for a purpose to be described. The strips of the u per series are pressed or otherwise formed into channel shape in cross section with the channel or open side extending downwardly .while the strips of the lower series are correspondingly formed or shaped but arranged to extend upwardly or in the opposite direction.

The springs indicated at 13 are of the double tapered type and are located between the upper and lower series of strips, the inmost convolutions of the springsbeingreceived within the channels of the strips. By this construction it is quiteevident that any lateral displacement of the springs is ab solutely prevented. i

The frame further includes upper and lower oppositely arranged elongated metallic strips 13 which are formedat intervals with knuckles 15 within which the outturned ends 12 of the strips 10 are engaged. Obviously, this engagement will positively prevent the strips 10 of the various pairs from separating and permitting the springs 13 to slip out.

The cushion further includes side walls 16 of flexible material disposed outwardly of the metallic strips 13 and secured thereto by riveting or otherwise as indicated at 17, it being preferable to provide reinforcing strips 18 of metal or even of flexible mate rial outwardly of the side walls 16 at the points where the rivets or other securing devices pass through, the purpose being to prevent ripping and make the structure strong. The side walls 16 may be prolonged and formed integrally with the seat portion 19, as shown in Figure 2 or separate pieces might be secured together, this detail being immaterial. The numeral 20 represents the usual padding which is interposed between the cover or seat 19 and the uppermost series of strips 10. Logically it is well Within thescope of the invention to provide a seat 21 of flexible material to cover the upper series of strips, 10 and the upper ends of the springs to further reduce any likelihood of displacement of the pad ding or punching through of the springs and their securing strips.

From the foregoing description and a study of the drawings, it will be readily apparent that I have thus provided a very simple and inexpensive seat construction in which all the parts are absolutely locked together so that displacement in any direction will be positively prevented. It is obvious that a seat constructed in accordance vention' orf the scopeofthe 'subjoined claims.

Having thus 'described the invention, I

I claim 1.
